Abstract: Mfr. of steel tools with high wear resistance and dimensional accuracy is described. Atomised powder of e.g. tool steel is compressed fully the thermal isostatic compaction to give a homogeneous structure. This moulding has the shape and dimensions of the finished tool. It is heated to over 1000 deg.C and coated with 1-12 microns 6-10 microns of one or more hard materials by chemical vapour depoution. This is an integral part of the heat treatment. This heat treatment provides a suitable base for the coating so that it does not some loose in impact. Also the homogeneous structure of the tool prevents it deforming during the chemical vapour deposition and heat treatment. (Provisional Basic previously advised in week 8343)

Abstract: A solid-state electrosurgical generator is disclosed which provides output waveforms that are optimized for electrosurgical fulguration. The fulguration output circuitry consists of a radio-frequency tank circuit which is periodically pulsed to produce a periodic damped-sinusoidal output waveform. However, the damping factor is sufficiently low so that many cycles of the waveform occur between periodic input pulses. Although the duty cycle is relatively high compared to prior art devices, cutting and burning effects are prevented by a high impedance output which internally limits fulguration arc current. The fulgurating arc developed by the device is longer and more consistent than that developed by previous devices thereby resulting in superior fulguration.

Abstract: This invention implies a design of a sewing machine in a rational way, where the bed shaft and the arm shaft have been replaced by a synchronous belt (19) and where the plane of rotation of the synchronous belt is perpendicular to the cloth feeding direction. The solution implies that all function units which drive or are driven by the synchronous belt and the belt itself are mounted on the same side of the sewing machine body which is a very great advantage in view of assembly technics. In the driving system there is a number of backing rollers (20-26) which guide the synchronous belt in the plane of rotation. These backing rollers are entered on shafts which are either stationary or driving. The shafts are then supported by the sewing machine body in rotation or stationary manners. The backing rollers can be smooth or toothed wheels which drive or are driven by the synchronous belt. Then, some toothed wheels can drive several function units of the sewing machine. By changing the diameter of the toothed wheels in relation to each other the time relation between the several function units of the sewing machine can be controlled. Another advantage with this invention is that the driving motor can be connected to one of these toothed wheels directly, thus driving the several function units via the synchronous belt without intervening primary transmission.

Abstract: The display incorporates a current supply source, and a drive (25) for controling the electrical current from the source to the individual light components, at the same time enabling light combinations to be formed via switches. Each light component or diode (4-10) receives a separate feed of current from the source by a number of lead connections, and the switches (53-59) are electronically controllable, being coupled in shunt connection. The shunt connections are parallel with each of the light components, and the switches are selectively opened or closed by separate control signals. When the shunt connection is open, the drive current passed to the corresp. illuminated. component so that it is maintained light When the connection is closed, the light component is extinguished. The drive has several inputs receiving control signals for the switches (53-59,37), and connected to the outputs of a digital computer (24). The computer output signals are in the form of low or high voltage levels to change over the switches from closed to open positions, thus extinguishing or igniting the light diodes.

Date Aug. 10, 1989.A method and apparatus for enabling refrigerants, preferably freons, to be emptied from refrigeration systems or heat pump systems with the aid of piston compressor pumps when repairing or scrapping such systems. The compressor suction line is connected to one chamber of a heat exchanger and a pressure reduction valve is connected in the suction line upstream of the heat exchanger. The pressure line extending from the compressor passes to an oil separator and then to the other chamber of the heat exchanger. The fall in pressure in the reduction valve and heating of the refrigerant in the heat exchanger causes the refrigerant to be in a gaseous state when reaching the compressor, which is a prerequisite for safe operation of the compressor. The pressure increase achieved in the compressor pump and cooling of the refrigerant in the heat exchanger enables the refrigerant to be delivered to a container, preferably in a liquid state.
